[[File:WiiDraw1.jpg|200px|thumb|right|Graffiti or something]] Because motion controls are awesome. == I/O == See also the [http://wiibrew.org/wiki/Wiimote Wiibrew article]. === Accelerometer === 3x 8 bit, for X, Y and Z. The readings include earth gravity (1G). Supported range is about -6G .. 6G, giving us a pretty bad precision of 0.04G. Useful for determining the absolute wiimote tilt state (pitch/roll/yaw) and throws (x=y=z=0 ⇒ "zero gravity" at the tip of a throw) === tilt sensors (MotionPlus) === [[File:Rotations.gif|200px|thumb|right|Axis names]] Roll, Pitch and Yaw, 16 bit per value. ''Only'' reports relative motion, earth gravity doesn't matter. Also, it only reports motion around the Wiimote's own axis. Moving the wiimote up/down/left/right on a straight line doesn't really affect the readings. Useful for pointing devices (works as good as infrared pointing) and detecting rotation (augmented reality). === Speaker === See [http://wiibrew.org/wiki/Wiimote#Speaker Wiibrew]. === LEDs === Four LEDs. The bluetooth connection is fast enough to implement software PWM with 10 brightness levels. === Buttons === Can be read via Polling and Interrupts. == Done == * Neverball: Wiimote is already supported, use [https://github.com/derf/wii-sensors/blob/master/neverball/tilt_wii.patch tilt_wii.patch] for balance board + wiimote support. Note that the patch is unstable and may crash while syncing. * pointing device: [http://abstrakraft.org/cwiid/wiki/wminput wminput] supports infrared and button controls. Using the MotionPlus, one can have infrared-behaviour without actual infrared LEDs. The patch is available in the [https://github.com/derf/cwiid/tree/mplus-pointer mplus-pointer branch] on github * Audio output with MPD interface (low quality) * interactive blinkenlights using the LEDs == Ideas == * Stepmania via Balance Board? (if it is precise enough) * Minecraft: Movement via Balance Board, wiimote as pickaxe * Use Wiimote as lightsaber (already possible for smartphones, but... whatever :p ) == See also == * [http://wiibrew.org/wiki/Wiimote Wiibrew article] about wiimote (more detailed) * [https://github.com/derf/wii-sensors wii-sensors] git repo === Videos === * Neverball with balance board: [[Has video::http://finalrewind.org/interblag/entry/neverball-balance-board/bboard2.mkv|mkv]] / [[Has video::http://youtu.be/cIIBW7j1lAQ|youtube]] * Testing Minecraft "Augmented Reality": [[Has video::http://lib.finalrewind.org/v/wiimote_minecraft.mp4|mp4]] / [[Has video::http://www.youtube.com/watch?v=9rj07tBJbyc|youtube]] * Audio example: [[Has audio::http://lib.finalrewind.org/v/wmsp_im.mkv|Imperial March]] [[Category:Projects]]
